Make "standard" ("extended") query evaluation mode the default

[abrokenjester]

Problem description

Currently the default query evaluation mode is "strict" on any newly created repository. This is unnecessarily restrictive: "standard" (previously called "extended") mode is fully compatible with the SPARQL 1.1 recommendation, and offers a lot of usability extensions, including extended support for calendar-type comparisons, and more.

Preferred solution

We should make "standard" evaluation the default so that every RDF4J user gets the benefits of the more extensive set of operators and functions that this mode offers.
